Who is speaking ?
•
José Ruy - Brazilian, from Belo Horizonte, Minas Gerais
•
Electrical Engineer, specialized in Telecommunications and
Computer Science by UFMG, with MBA in project management
by FGV
•
In the telecom industry for over 11 years
•
Product Manager of an OSS-Based solution software
•
This software won as the best one in its category in well know
events of the industry in LATAM (2016), MENA (2017) and
Africa (2017)
QoS, QoE: something to think
•
Are the networks working 100% with no fails ?
•
If the network has no fails, QoS = 100%, what would be the
QoE ?
•
And if still the QoE is not 100%, what can you do ?
QoS: what can we do to improve it
•
A good network performance is the 1st step
•
Problems can be basically at the network, the UE or the
interfaces (air, fiber)
•
We will tackle Network problems
OSS Data
end-to-end
OSS – Operation Support System
OSS – Data Reporting
OSS – What Data
•
CM: Configuration Management
•
PM: Performance Management
•
FM: Fault
•
TM: Traces
•
LM: Licenses
•
HM: Hardware
Equipment with no OSS
CORE, Microwave, IP
Equipment with no OSS
Equipment with no OSS – Data Reporting
Network Monitoring
End to end
Network Monitoring End to End
•
Many different equipments
•
Unified view: reduce complexity
•
Use Case: operator NOC – Network Operation Center – 24 x 7
Use case: Unified View
Network Monitoring End to End - Identify
•
Something is outside the thresholds
•
Something is outside the normal behavior
•
Something will probably be outside the normal behavior
Network Optimization
Solving the problem
Network Optimization – solving the problem
•
Found the bad performance element, what now ?
•
Too much data… Correlation! PM, CM, FM
•
But… What if the
problem is not in
the element itself ?
CM change found!
Network Optimization
End to end
Network Optimization – end to end
•
Use case: transmission affecting cell downlink throughput
